Manual Extract (Tier 2): Steering pressure limit setting

With the engine at high reves, the pressure of the port P of the tool distributor must be between 239 and 243 bar:
– make sure that the pressure value stated in paragraph A is as specified (22-25 bar); – with the engine OFF and bucket on the ground, connect a quick coupling pressure gauge to the pressure point P of the tool distributor; – with the articulation locked, engine at high revs and JSS ON begin steering with the joystick in both directions to its limit stop. Keep this condition and read the pressure value on the pressure gauge, which must be equal to that specified above (239 and 243 bar);
– if the pressure gauge records a pressure above or below the specified one, check that all the hydraulic connections have been made correctly.

The speed of steering is not constant but depends on the speed reached by the vehicle. On reaching 20 km/h the steering sensitivity is reduced by 80% compared to the normal speed of steering.
The JSS can be set on three different levels of steering speed.
The three speed levels are:
1. from 4.5 to 5.5 sec.*
2. from 3.2 to 4.5 sec.*
3. from 2.8 to 3.2 sec.*
*(time to take the unit from all right to all left).
